DARPA Hopes Automation Can Create the Perfect Hacker

Seven Pentagon supercomputers are getting ready to attack one another. Look out, human hackers. Pentagon research agency DARPA says people are too slow at finding and fixing security bugs and wants to see smart software take over the task.

The agency released details today of a contest that will put that idea to the test at the annual DEF CON hacking conference in Las Vegas next month. Seven teams from academia and industry will pit high-powered computers provided by the agency against one another. Each team’s system must run a suite of software developed by DARPA for the event. Contestants win points by looking for and triggering bugs in software run by competitors while defending their own software.

Mike Walker, the DARPA program manager leading the Cyber Grand Challenge project, claims the approach could make the world safer.

“The comprehension and reaction to unknown flaws is entirely manual today,” he said in a briefing Wednesday. “We want to build autonomous systems that can arrive at their own insights about flaws [and] make their own decisions about when to release a patch.”

When a malicious hacker finds a new flaw in a piece of commonly used software, they can typically exploit it for a year before it is fixed, Walker said. “We want to bring that response down to minutes or seconds. Hopefully we ignite a revolution where we eventually have a machine that can compete with top experts.”


The seven competing teams were selected last summer after a simpler, preliminary contest. Each team was given $750,000 and access to a high-performance computer with 1,000 processor cores and 16 terabytes of memory.

In next month’s final contest, teams must sit back and watch as the software they have developed competes against that of the other contestants without any human intervention. The winning team will take home $2 million and be invited to compete against human hackers in DEF CON’s annual capture-the-flag contest.

Walker doesn’t expect the automated hacker to do very well against humans, but the software doesn’t have to be able to hold its own in a matchup with elite hackers to be useful. Anything that helps the U.S. military find flaws in its software faster would benefit national security, he said.

He played down suggestions that technology developed for the Cyber Grand Challenge could be used maliciously in the real world. Not only is it unclear whether techniques developed for the contest would work on real software, but DARPA is committed to encouraging wide use of such software, said Walker. Teams are required to release all their code as open source.

“If technology is democratized, then we don’t believe that nefarious misuse will be feasible, because the bugs that will be found will already have been patched,” he said.
